通过“从库中新建模型”，您可以插入库中已创建的模型，请参见{%！
When you click on the
button, the Model Library Manager opens. The model library contains simple 3D objects, such as a block, cylinder, sphere, cone, and so on. These models can be further modified after insertion, for example, their dimensions can be changed graphically. By stacking these simple objects, a more complex model can be created quickly using the "Merge models" function. The model library can be expanded gradually with custom objects.
Information about the current library is in Model Libraries; here you can add new libraries and edit the existing ones.
